I don't think it's disinfo. The link is to an English version of a story from TT News Agency, which is apparently similar to AP, but in Sweden. It's the main news wire in Sweden.

However, the original source is Telegram videos by the groups, which have since been deleted. It was reported in Italy, and now Sweden. I don't think it's disinfo, it's just not real attribution.

We are not supposed to editorialize here, or I would have tried to make that more clear in the title.
